Firearm Spade Grip Assembly for Easier Handling and Stable Firing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms, such as rifles or light or medium machine gun-style firearms, are large, heavy, and unwieldy, making effective use difficult due to their significant size, weight, and shape, which complicates carrying, shouldering, and accurate firing.
Innovation Solution
A firearm spade grip assembly comprising a paddle trigger assembly and mounting system that allows for convenient actuation and firing by translating an actuator in an aft portion, with a paddle trigger safety to prevent accidental actuation, and a mounting system that stabilizes and pivots the firearm for easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional firearm is used, then the firearm can perform its primary function of firing, but it becomes difficult to carry, shoulder, and fire accurately due to its size and weight
Solution Approach 1:
The firearm system is divided into separate components: a lightweight spade grip assembly with paddle trigger that can be independently mounted on the firearm receiver. This segmentation allows the heavy firearm body to remain separate from the handling components, enabling easier manipulation without requiring the user to support the entire firearm weight.
Solution Approach 2:
The spade grip assembly acts as an intermediary between the user and the heavy firearm. The mounting system with support arms and joints provides a mechanical interface that transfers control forces from the user's hand to the firearm, eliminating the need for direct manual support of the firearm's full weight during operation.
2Ease of operation
If the firearm is made more manageable through mounting systems, then ease of handling improves, but the device complexity increases
Solution Approach 1:
The spade grip assembly integrates multiple functions into a single compact unit: the paddle trigger provides firing control, the spade grip offers a stable holding surface, and the mounting interface attaches to the firearm receiver. This multi-functionality reduces the need for separate components, thereby limiting the increase in overall device complexity while achieving improved ease of firing.
Solution Approach 2:
Instead of attaching the heavy firearm to a lightweight handle (traditional approach), the invention inverts the relationship by mounting a lightweight spade grip assembly onto the heavy firearm receiver. This inversion allows the firearm's own weight to provide stability while the lightweight assembly provides ergonomic control points.
3Ease of operation
If a paddle trigger assembly is added to enable convenient actuation, then ease of operation improves, but the device complexity increases
Solution Approach 1:
The paddle trigger assembly merges the trigger mechanism with the spade grip structure into a single integrated component. The paddle trigger is positioned on the spade grip body, eliminating the need for separate trigger housings and linkage mechanisms. This merging reduces the number of parts and simplifies the overall assembly while maintaining full firing functionality.

AI summary
A firearm spade grip assembly can comprise a firearm, paddle trigger assembly, and/or a mounting system. A paddle trigger assembly can comprise a base spanning between and comprising a base forward end and a base aft end; a paddle trigger coupled to the base; a trigger actuator coupled to the base; and/or an actuator housing coupled to and extending forward from the base, wherein the trigger actuator is disposed at least partially within the actuator housing. Movement of the paddle trigger can be configured to translate the trigger actuator. A mounting system of a firearm spade grip assembly can comprise a mounting base configured to couple to a firearm receiver base or a firearm receiver of the firearm.
